Why it works: Parsley and shallot match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 3,737 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓

Ingredients
Directions
Prepare
Beat the eggs with cream, parsley, shallots, green onions or chives, pepper, and salt.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into the structure of the omelette as they cook.
- Cream
- Adds moisture and tenderness to the cooked eggs.
- Butter
- Fat for frying that adds flavour and helps prevent sticking.
The step that matters
Stirring the eggs as they set. Stirring while the eggs begin to set forms small curds that keep the omelette tender. Letting it sit too long without stirring can make it tough and overcooked on the bottom.
Swap the onion
How well each one fits the dish's main ingredients (egg, cream, parsley, shallot, pepper, butter):
- Chivefits better
- Leekfits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against egg, cream, parsley, shallot, pepper, butter. Candidates are from the same food group and used in at least 100 recipes.
